With the increasing prevalence of 3D videos, understanding distinctions between 2D and video experiences has become significantly important. In our study, we explored cognitive load imposed by stimuli under various tasks using electroencephalogram (EEG) data. To assess load, introduced Cognitive Load Index (CLI), a measure that combines oscillations theta alpha oscillations. Our experimental setup included four stimuli, each associated with typical tasks. Participants were exposed to both during which their EEG data recorded. Then, analyzed power within 0.5-45Hz frequency data, CLI used evaluate brain activity. According experiments analysis, videos requiring simple observational (P < 0.05) consistently induce higher in participants when watching videos. However, for involve calculation > 0.05), difference induced is not as pronounced. Thus, conclude generally but extent this also depends on content stimuli.
